Emissary Reward increase on patch day?

I’m wondering if gear rewarded for emissary quests will increase on patch day.
I don’t want to turn in today for a 415 piece of gear if the reward will have a higher item level after the patch.

Any definitive info on this? Tvym

From this post:

It looks like the item level bump happens with the start of Season 4, which is Jan 21st.
